… and how to get rid of it.
[update 02/05/2018 The information how to create camera noise profiles is outdated please read this tutorial instead!]
[update 20/12/2012: ‘how to profile your camera’ includes instructions with the new gen-profile script]
[update 15/12/2012: no more recompile needed, updated the instructions in the benchmark section and how to run make.sh.]
to summarize the current situation in dt: we have a lot of cool tools wrapped around great algorithms with almost all the knobs you need to get perfect results. while you can actually get really great results it’s this sheer number of knobs that makes finding a good parameter set quite a time consuming task. even creating per-iso presets is not straight forward, as most of the current modules depend on a lot more stuff early on in the pipe (whitebalance, exposure, basecurve, etc).
